ecocrop: Ecocrop model

In dismo: Species Distribution Modeling

Ecocrop model

Description

Very simple mechanistic model for plants.

Usage

ecocrop(crop, tmin, tavg, prec, rainfed=TRUE, ...) 
getCrop(name)
data(ECOcrops)

Arguments

crop	An object of class 'ECOCROP', or the name of a crop as in getCrop
tmin	Vector of monthly minimum temperature (degrees C)
tavg	Vector of monthly average temperature (degrees C)
prec	Vector of monthly precipitation (mm)
rainfed	Logical. If FALSE, the crop is assumed to be irrigated
...	Additinal arguments
name	Name of a crop (character). If missing a data.frame with all crop names is returned

Value

Object of class ECOCROP

Examples

ecocrop('potato', 5:16, 15:26, runif(12)*100)
getCrop('Acacia brachystachya Benth.')
crop <- getCrop('Hot pepper')
ecocrop(crop, 5:16, 15:26, rainfed=FALSE)

# with spatial data
tmin = tavg = prec = brick(nrow=1, ncol=1)
tmin <- setValues(tmin, t(matrix(5:16)))
tavg <- tmin + 5
prec <- setValues(prec, t(matrix(15:26)))
crop <- getCrop('Hot pepper')
ecocrop(crop, tmin, tavg, prec, rainfed = FALSE)
